HR due diligence in most transactions is run as a document request. A list goes out, folders come back, an adviser produces a summary describing what was found, and the summary changes nothing — because it describes the target's HR function rather than quantifying the exposures that belong in the price.
The useful version asks a narrower question: which findings adjust consideration, which need an indemnity, which need cash held back, and which are integration costs the buyer will carry regardless. Everything else is background.
Four workstreams
| Workstream | What you are quantifying | Where it lands |
|---|---|---|
| Employment cost and liabilities | Obligations already accrued but not funded or not recorded | Price adjustment |
| Compliance exposure | Historic non-compliance and its look-back period | Indemnity or escrow |
| People risk | Who leaves, what they take, what triggers on change of control | Retention budget; occasionally a walk |
| Integration cost | Harmonising pay, benefits, systems and terms after close | Buyer's cost, modelled in the plan |
1. Employment cost and liabilities
The recurring finding across Indian transactions is that end-of-service obligations are recorded but not funded. Gratuity is an accrued liability that many mid-market companies carry unfunded, provisioned on an actuarial basis that may or may not reflect actual service records — and the underlying service data is frequently worse than the provision implies, because joining dates were migrated between systems at some point and nobody reconciled them.
What to quantify, in order of how often it is understated:
Gratuity or end-of-service provision against actual service records. Not against the actuarial report — against a service-date extract. In the UAE, end-of-service benefits accrue on a service-length formula and are similarly often unfunded.
Leave encashment liability. Accumulated balances, valued at current salary rather than at the salary when the leave was earned.
Unpaid or under-paid statutory contributions. Provident fund, ESI and professional tax arrears, plus the interest and damages that attach to them. These accrue automatically and are rarely provisioned.
Equity overhang. Outstanding options, the vesting schedule, acceleration on change of control, and whether the pool has been topped up in a way that dilutes the buyer post-close. Read the plan document, not the cap table summary.
Variable pay in flight. Bonuses accrued for a period ending after close, and commissions on pipeline that will convert under the buyer.
2. Compliance exposure
This is where the money is, because exposure is a function of how long an error persisted rather than of its size in any one month.
| Exposure | Why it compounds |
|---|---|
| Contractor misclassification | Reclassification brings retrospective contributions, interest and damages for the whole engagement period, not the current year |
| Statutory contribution arrears | Interest and damages run from the original due date |
| Wage-structure composition | Structures built to minimise contributions face recalculation exposure; the Code on Wages changed the definition of wages |
| State registrations | Operating in a state without registration is often discovered only in diligence |
| Singapore CPF underpayment | A wrong rate applied consistently — an age band or PR year missed — compounds silently and is recovered with interest across the whole period |
| UAE wage protection history | Late-payment history now carries category downgrades that raise the cost of future transactions for the acquired entity |
3. People risk
The question is not the attrition rate. It is which individuals hold value that transfers with them, and what the transaction itself does to their incentives.
Concentration. Which relationships, technical knowledge or regulatory licences sit with one person. Map revenue and delivery dependency to named individuals, then check what those individuals' contracts say.
Change-of-control triggers. Accelerated vesting, retention payments, severance enhancements, and good-leaver definitions that become generous on a transaction. These convert directly into cash at close and are often missed because they sit in individual contracts rather than in the standard template.
Restrictive covenants. Their existence matters less than their enforceability, which varies sharply by jurisdiction. Indian non-compete provisions operating after employment ends are generally difficult to enforce, so a seller's assurance that key staff are locked in deserves testing rather than acceptance.
Post-close intent. Where the deal structure allows, the retention conversation should happen before signing rather than after. A retention budget set after key people have decided to leave is money spent late.
4. Integration cost
This is not a liability of the target, but it belongs in the model and is routinely omitted.
Harmonising salary bands upward is the single largest item and is almost never optional once employees compare notes. Benefits alignment follows. Then systems: migrating payroll history, tax positions, leave balances and vesting schedules into the buyer's stack, with the same data-quality risk that makes every migration estimate optimistic. Finally, any redundancy programme, priced with statutory notice and severance in each jurisdiction.
The document request that actually produces answers
| Ask for | Because a summary will hide |
|---|---|
| Employee master extract with joining dates, entity, state and status | Service-date errors that under-state gratuity |
| Twelve months of statutory challans and filing acknowledgements | Late or missed filings, which a compliance certificate will not show |
| Full contractor register with engagement dates and scope | Misclassification, the largest single exposure in most Indian targets |
| The equity plan document, not the cap table | Acceleration and leaver terms |
| Non-template employment contracts, listed by exception | Individually negotiated change-of-control terms |
| Actuarial valuation plus the underlying service data | A provision built on data nobody has reconciled |
| Any notices, inspections or disputes in the last three years | Live exposure the seller considers immaterial |
Turning findings into deal terms
Quantified and certain — an unfunded gratuity liability, an accrued bonus. Price adjustment.
Quantified but contingent — a misclassification exposure with a defined look-back and a probability of assessment. Specific indemnity, usually with escrow, and a cap negotiated against the size of the look-back rather than the current-year figure.
Unquantifiable but material — a key-person dependency, an unresolved dispute. Retention structure, deferred consideration, or a condition to closing.
Buyer's own cost — harmonisation and systems. Model it; do not attempt to charge it to the seller.
What HR due diligence does not tell you
It will not tell you whether the two organisations can work together. Every measurable thing in this article is a liability or a cost, and the reason acquisitions underperform is more often cultural and managerial than actuarial. A clean HR diligence report is a statement that you have not found expensive surprises, not a prediction that integration will succeed.
It also will not surface what the seller does not know. Most under-provisioning we have described is not concealment — it is a company that genuinely believed its service dates were right because they came out of a system that had been migrated twice. Which is the practical argument for asking for raw extracts rather than reports.
Frequently asked questions
When should HR due diligence start?
Early enough that findings can affect structure rather than only price. Contractor misclassification and unfunded end-of-service liabilities can change whether a share purchase or an asset purchase is preferable, and that decision is made early.
What is the most commonly under-provisioned item in Indian targets?
Gratuity, followed by contractor misclassification exposure. Both share a cause: the liability accrues quietly and nobody is confronted with it until a transaction.
Should we speak to key employees before signing?
Where the process allows it, yes — retention conversations after announcement are markedly harder. Whether it is possible depends on confidentiality and the seller's willingness.
How far back should the compliance look-back go?
Far enough to cover the limitation period applicable to each statutory exposure in each jurisdiction, which is not uniform. Take this from counsel rather than from a rule of thumb.
This is a diligence framework, not legal or transaction advice, and it contains no benchmark claims. Statements about the enforceability of restrictive covenants, limitation periods and statutory look-back exposure are general characterisations and vary by jurisdiction and by facts — take them from counsel.
